Hi all,

Today's qemu boot log shows 256k extra in reserved memory:

- Memory: 2046080K/2097152K available (14720K kernel code, 2944K rwdata, 18048K rodata, 5184K init, 1431K bss, 51072K reserved, 0K cma-reserved)
+ Memory: 2045824K/2097152K available (14720K kernel code, 2944K rwdata, 18048K rodata, 5184K init, 1439K bss, 51328K reserved, 0K cma-reserved)

I don't know what has caused this.

Cheers,

Assuming it's pseries, it's the RTAS work area allocator reserving the
memory.

43033bc62d34 powerpc/pseries: add RTAS work area allocator

Yeah, pseries_le_defconfig.  Thanks, I will stop worrying about it.
